I think the display is nicer on them. 100% wide doesn’t work on mp3 from usb for 850, but does for 900. I also don’t think the 850 has link, so you have to use two usbs if you use them. I do on my 400s and its a bit annoying to manage two thumbs.
I don’t think I would ever use the wide pitch and 2 USB sticks really don’t bother me I know the display is a bit better on the 900 (I.E more lines) but even with all thos little extras I can’t convince myself to drop that extra £500
i dunno i’d give them a try. The 900s are really really nice. That would be my go to set of cdjs. But the 850s are definitely awesome as well, can’t really go wrong at that range. I think I’m upgrading to 900s, or 2000s next year.
I had the 900’s, great little units, but sold Them since I wasnt making full use of the rekordbox feature, I mean I was merely using them as midi controllers to be used with traktor and I was thinking to myself “hey do I really need CDJs for this?” and sold them, bought myself a brand new MacBook pro and a traktor kontrol s4 with the money I got from selling them off , not a bad trade I’d say!
If you plan to use software altogether with the CDjs I’d say get the 850s as you won’t really use the extra features anyway
